Please note that when switching an app between free and paid, your position in the rankings resets. If you get 1 million free downloads, and change your app to paid the next day, none of those downloads count in the paid charts ranking algorithm. (At least, in the past it hasn't)
That's good to know, thanks. Based on a previous launch, I was under the impression that they wouldn't reset. But it certainly does make sense that they do reset when going from free to paid.
